I went straight under the interstate and there was a white marker but seemed to be over grown, i went anyway apparently the trail head was a few yards away because i found the trail, it's a well traveled trail but could use a fresh coat of paint on the blazes.this loop is listed as moderate, if you want more of a challenge then find the blue trail, it's not a loop and comes with a warning.when i hiked it was foggy and drizzling, add that to some snow and wet leaves it was rather treacherous no matter what trail you hiked.
